2019 Hyundai Elantra engine noises

[@kaganhudayar630]

My 2 cents; My wife has a 2013 which started making this noise around 100K. Checked the oil, and it was low. Added oil, it went away. A couple weeks later, it came back. Checked oil, low again. No leaks anywhere. Checked for gasket issue, no. Antifreeze clean, exhaust fine. From then on, I made sure to keep extra oil in the trunk, and found she needed a quart every 500-750 miles. Dealer said it was normal for this vehicle. One day I had no other choice and had to add 5W30 as that was all I had on hand, and she was slapping like crazy. It went away completely. Then I did a full oil change with 5W30 and checked weekly for low oil. No low oil. 6 months went by, and it didn't lose a drop of oil. Did another change, and still fine. Now has 180K and pulls strong, little bit of noise starts returning after a long while, which usually just indicates time for a change. The 0W20 / 5W20 which is recommended is for fuel economy. However, it's so light, it seeps into the chamber and burns up. The pistons become dry and rattle. As oil runs low, the damage intensifies. My advice - run 5W30 in it always. It is the standard weight recommended for similar engines from Honda and Toyota. Hyundai did this to beat them on fuel efficiency, but it damages the engine in the long run. You'll get 27-30MPG instead of 30-33, but so what? I'm convinced this engine would have crapped out by 125K if I hadn't switched to the 5W30. Also Castrol Edge full synthetic runs the quietest, cleanest, and doesn't burn up. I've tried every brand. In this case, the Castrol is best.

Thank you for sharing

Did you try royalpurple

[@woodyallen570]

This is happening rn and my car is stalling any more tips?

[@kaganhudayar630]

@@woodyallen570 How bad is the piston noise? This car also burns up ignition coils because the oil seeps in to the plugs and coils. That's a possible cause of stalling - fouled plugs. I've had to replace O-rings, then did a full plug and coil replacement. Maybe an hour's work at most. Pull the coils first. You'll notice greasiness at the bottom with misshaped, or floppy rubber tips. You'll eventually have misfires and codes from this. I'd look at that first.

[@kaganhudayar630]

@@davidrueda1617 Yes, though not every one. Castrol Magnatec was the first to quiet it. Can't get this anymore, but Castrol Edge full synthetic has the same additives.

[@scott4172]

That sound is piston slap. These engines are known for it.

[@erinarnold6697]

Does it have a mechanical fuel pump? Sounds like it’s the roller wheel on the cam.

[@dads85]

that sounds coming from the valve tappet\ lifter

[@italktoomuch]

Mine works and sounds the exact same. I’ve heard other cars and they sound the same too. Although loud I’m pretty sure it’s normal. It tends to go fully away once the engine is hot.

[@soonkeelee3914]

Sorry for answering so late... Been busy with life, car.... I took my car back to the dealer I bought it from. The service advisor didn't even want to listen to my video and told me that is normal and his Hyundai sounds the same... I called Hyundai and they create a case for me and ask me to take to any Hyundai and give them the case number. I went to another Hyundai dealer that we bought 4 cars from before and they took my car in (3-13-2021). I drive my Son's 2018 Hyundai Elentra temporary for a few days. A few days later, they called me and told me my engine is defective (cylinder 2, 3 I think) and they are going to ask Hyundai for a new engine. I asked for a loaner car and they gave me one. Pick up loaner car on Saturday (3-20-2021) Now, I am waiting for them to receive my new engine and put everything back for me. TX is having snow freezing issue that cause most of the delay. Hyundai told me my car should be ready around 4-3-2021. I will post more update as soon as I get them.

[@soonkeelee3914]

btw, my car has 19,000 ish miles.

[@italktoomuch]

@@soonkeelee3914 interesting. maybe i might look into it. my car is already at almost 40,000 miles though and has worked perfectly anyway. i use it for lots of highway driving and mountain driving so if it were do break down i feel like it would’ve already happened.

[@starcityrc3298]

My 07 Ford Focus sounded exactly the same. Just got a 2017 Hyundai Elantra SE. Pretty standard 4cyl sound. Noisy injectors

[@nanakodjo4595]

Exactly

[@giorgigkebadze184]

Hello, if possible, tell me what the problem could be with the engine of my car making such a sound

[@HersheyRoseX]

With high quality oil the sound dissapears. Also with this engine in the manual it says 5w-20 is preferred 5w-30 and 10w-30 above -4F. Amsoil Signature Series 10w-30 is what I run with 87,600 miles. Also when you are warming up your engine don't rev 😬(personal opioion.)

[@Exotixa69]

It’s the Cadillac converter rear one!!! With the flex pipe my car had the same problem until I replaced the converter

[@jackyputman6399]

My 2019 sounded the same its piston slap and I just got a new engine in mine under the recall that just got released

[@emmanuelkowalski4157]

Where did you find the recall

[@soonkeelee3914]

@@emmanuelkowalski4157 Call Hyundai, don't go to dealer.

[@jaxandmore440]

These engines are known to have defective ignition coils that can cause excessive detonation (pinging sound while accelerating). I wonder if prolonged detonation over many miles can eventually lead to this engine ticking noise. I have 23k miles on my 2018 Elantra with bad ignition coils, but the dealerships refuse to do any warranty work until the check engine light comes on.

[@kaganhudayar630]

Same with my wife's 2013. I keep spare coils in the trunk. As soon as you feel the tell-tale misfire, swap them out. In hers it's always #2 that goes bad, so likely not the coil itself, but possibly due to malformed cylinder? You can find aftermarket coils for fairly cheap and just swap them out in like 4 minutes. I've done it on the side of the road.

[@alexcote3289]

I got warranty and my dealer say its a normal sound just be cause the sound change when is warm up he dont want to change short block :(

[@matttheroux4769]

mine does the same and it burns oil like crazy. took it took dealership and they wont help. i'm going to trade t in this week with only 14000 miles on it. its a 2020. I cant wait to get rid of it and get a corolla.

[@Nikitos253]

Your engine is dead they should diagnose and replace the engine under warranty that issue is common with all Kia/Hyundai engines it's called piston slap class action lawsuits is going for years for different models just don't buy Korean cars

[@cic-jakevanddalgeemyers.2739]

It's the VVT solenoid.

[@timbuktug3321]

My 2020 Elantra does that too.

[@jairorivas078]

Alguien me ayuda . Mi primer encendido en mi Hiunday Elantra 2018 suena así feo y luego lubrica y se le va el sonido . No me gusta que sea así tiene el aceite de fabricante 5w-20

[@henispatel8537]

mine is 2018 Elantra. have same noise. Deal doesnt recognize my Issue. i have around 75k Miles (120k km - canada). Dont have any more warranty on it. should I see it?

[@alexcote3289]

Same for me never buy a hyundai again

[@soonkeelee3914]

You should contact Hyundai directly. Most dealers don't want to deal with this.

[@IMANISINGH884]

Yo mine do same shit. I have 127k on it. What you did? Can u contact me I want your help

[@leelewis1294]

Piston slap is from cold engine driven not good let your hyundai gdi warm up before you drive off not enough oil was at the top of the cylinder causing the coating on the Piston to burn off

[@scott4172]

This isn’t a GDI engine.

[@soonkeelee3914]

Hyundai eventually recall all the Elentra from 2017 to current. If you own these cars, contact Hyundai and hopefully they will swap out your engine like what they did for me. I no longer own the Elantra. Good luck to you all.

[@danieldelvalle6780]

I hace 2019 the sale sound and one day i Washington more Hard and is Washington the alternador i Washington thinking my motor is broke

[@sonsofguns1903]

I had a 2016 Elantra, the noise started at 68000 miles. I thought it was just a bad valve. I got rid of the car. I bought a 2019 Elantra, the same thing is happening at the same amount of miles, I have 68 thousand miles and it is doing the same thing. I'm taking it to the dealer

[@masterfox3539]

Just don't buy elantra man I just wanna get rid of this ridiculous brand

[@mustafa2920]

My car 2013 only 67 mile same issue

[@michaelfavila4413]

What happened to your engine what is the cause of knocking? Is it in the piston or valve?

[@gibfkn]

What did the dealer said it was the problem? Also, does that sound goes away after the car warms up?

Yes, the ticking sounds go away after the engine is warmed up.

[@gibfkn]

@@soonkeelee3914 That's very good they're fixing you car for you now. Unfortunately, my POS Elantra started doing that after the warranty expires.

[@JP-uu2rw]

KZbin: My engine is making noise so let's race the crap out of it. If the noise is not present at normal operating temperature, don't worry about it. The fact you keep revving the engine when the condition present will exacerbate the situation. These engines are normally a little noisy anyway.

[@I4NI_]

Piston slap - the real reason that every Hyundai does this is the oil pumps are bad from factory.

[@Channel-cm7yc]

The oil pump isn’t the problem.

[@I4NI_]

@@Channel-cm7yc then it's vvt solenoid or exhaust cam. I just experienced this and spent over 4500 to diagnose. It was tough.
